Michelle Williams in Raimi's Oz

Variety reports that Williams is in talks with Disney to play Glinda the good witch in Oz The Great And Powerful. "Williams' character would team up with snake oil salesman James Franco to face off against her evil sisters, played by Rachel Weisz and Mila Kunis, in a power struggle for control of the magical land of Oz," according to the trade.

Director Sam Raimi reportedly didn't want Williams for the film. He is said to have wanted to cast Oscar winner Hilary Swank in it (with whom he'd previously worked with on The Gift), but Disney demanded that Williams play the witch role.
